The head of Roscosmos Borisov named the reason for canceling the launch of Angara A-5

It has been rescheduled for Wednesday.

The first launch of the Angara A-5 launch vehicle from the Vostochny cosmodrome, planned for Tuesday at 12.00 Moscow time, was postponed to a reserve date, that is, on Wednesday. This was announced immediately after an unsuccessful attempt to lift a 760-ton launch vehicle into the sky by the head of Roscosmos, Yuri Borisov.

Yuri Borisovich also reported the reason for the postponement: “The automation canceled the process due to a failure of the pressurization system for the oxidizer tank of the central unit. In this situation, the start is postponed to a reserve date, tomorrow.”

Let us recall that the rocket was supposed to launch with a new Orion upper stage and a test payload, which had to be launched into an orbit close to geostationary, that is, to an altitude of about 36 thousand kilometers.

However, the system canceled the start literally in 2 minutes, immediately after the command: “Oxidizer filling has ended.”

The Angara A-5 rocket produced by the State Research and Production Space Center named after. Khrunicheva should replace the only heavy Russian launch vehicle Proton. It is distinguished from the Proton, which flew on harmful heptyl, because of its environmentally friendly fuel and modularity.

Previously, the Angara was withdrawn only from the Plesetsk cosmodrome. The difference between launches from these cosmodromes lies in the launch capability: from Plesetsk, satellites can be launched into lower orbits, from Vostochny – into higher ones.
